Calculate split times

It is always an advantage to know your optimal split times during more serious training sessions.

If you are running a fitness race with an expected finish time of 44:30 min for 10 km, the tool helps you calculate your split times along the way.

You can decide yourself how often you want split times.

Once you’ve played with this calculator, I think you should do as many others have done and take a look at the others.crisp running calculators and maybe look at one of the different free running tools, which I have developed here on this page.

How I personally use split times for my running training

I have been running competitively for a few years. I like running with GPS running watches, but during competitions I try to use a very light running watch. This is to minimize inconvenience, disruption and weight. The simple running watches typically do not have much more content than total time and split times. I always save my split times on the watch to see my speed development afterwards.

The reason I find the split time calculator particularly useful is when I’m running a race and want to know in advance how fast I should run each kilometer. For example, if it’s a flat 10 km course, I’d like to know what times I should run after 1 km, 3 km, 5 km and 8 km. That way I can see if I’m running at the pace I estimated would be my best pace.

What difference does calculating split times make?

This is a personal observation. Having split times along the way in my running training makes me aware of my pace, but not more often than every kilometer. I can quickly analyze whether I have run too fast or too slow based on my split times at the kilometer markers.

If you prefer to run with a heart rate monitor with GPS or just a GPS running watch, the calculation of split times is also useful as you can see if you are at the right pace. Sometimes GPS watches are inaccurate, and it is my experience that their display and results should be taken with a grain of salt.

Recommendation for split times and example shown

Below you can see an example entered into the calculator, and based on that see the given split times – we recommend that you choose 1KM intervals as this gives the most accurate picture from the calculators.
